    Default zmrestore from ZCS 5.0.13 to ZCS 6.0.8

    I have a single live unit and have also set up a dev cluster suite. The live unit is on ZCS 5.0.13 and the cluster was set up and a backup was restored initially with ZCS 5.0.13 and now upgraded to 6.0.8.

    Before cutover I would like to then restore a last incremental and full backup from the standalone to the cluster but was wondering if there will be any issues doing a zmrestore?

    Welcome to the forums,

    Self quote:

    We’ve always recommended that: “After upgrade, you should run a full backup immediately as changes in this release invalidate all old backups.” It’s still good advice to have a fresh full, but there’s always the infrequent need to get data from an older minor version backup without throwing up a temporary machine. Well, with 5.0.x we aimed to make restores compatible across patch releases (i.e. an older 5.0.x backup, not a prior 4.5.x backup – major version restore is this RFE). There was a bug about zmrestore not handling database schema changes, but that’s fixed in 5.0.5 and later – so backwards compatibility for restore is now theoretically possible. And we’re also looking to put icing on the cake by adding a conversion tool to upgrade backups themselves to allow restore on later ZCS versions.

    Certainly can 'try it' but don't be super disappointed if it doesn't work, as bug 15750 is still open afterall. (ie: Might have to put 5.0.13 back on the dev setup if you need to get at that particular backup in the test area.)
